Answer 1:The desk clerk received $30 minus $5, that is,
$25; the bellhop kept $2; that is altogether $27 on one side of
the ledger. On the other side are the expenses of the guest,
namely $30 minus $3, also equalling $27. So there is no deficit
from the bookkeeper's angle, and no dollar is missing. Of
course, if you mix up receipts and expenses and add the guest's
expenses of $27 to the dishonest bellhop's profit of $2, you end
up with a sum of $29, and a misleading question.

Answer 2:The dealer was right. The car that brought him a 25 per cent
profit cost him $600 (because 600 + 25% = 750). The other car on
which he lost 25 per cent cost him $1,000 (because 1,000 - 25% =
750). So the dealer paid a total of $1,600 for two cars which he sold
for $1,500, causing him a loss of $100.

Now the question is: If the guest gets a refund of $3 he
had paid $27 to the hotel all told.

So hotel gets 30less 5 or 25, bellhop 2, and the client the refund of 3.

What cant you count ?

2.

percentages are cumulative. so 25% profit is based on a number less than 750 plus a percentage. So the 'base' number is less than 750 dollars. 25% loss is based on a number greater than 750 less a percentage, so the base number is more than 750.

Thats why percentages in terms of profit and loss are not trusted in industry. Those of us with any brains work in GM - Gross margin, which is an actual dollar value.
